After a couple days of research……
Wind in our area is AVG 8-10 MPH.
Most homemade wind turbines only work in 13mph or higher. So homemade power is out. However…
Talks about the new Honeywell wind turbines that can produce electric in as little as 2mph. They also can mount to a roof easily.
So this makes me think, that you could possibly to a solar/wind mix for power, keeping the genny as a backup.
Although the cost of this is high. I am leaning towards the idea of a power trailer.
This would allow us to position the system where the best sun and wind would be. This allows it to also be used in an offsite building location if needed, and keeps the house from having to be damaged installing equipment.
Just some thoughts.
